This invention relates to hat forming nniohines, und more ated hat' presses.

Theei und other advantages will loe more clearly understood i on upward hy reference to the accompanying' drawings, which illustrate the preterred ,t'orni 'of the machine. However, minor changes may he f made without the invention. l

3l is n tuhe for admitting` liquid tothe lio ing material is placed upon the lower die upper die'member into contact with the.. vlower. die member.

Further depression of the treadle 14 causes the frame 8 to descend, increasing the tension of the springs 26 and forcing the die member 24C into more intimate contact with the hat material and moving the `piston 30 downward in the cylinder 29, displacing the fluidtherein so as to cause the bag 28 to bulge and force the hat material into conformity with the walls of the recess in the lo'wer die member 27 to form the crown. The operation ofthe treadle performs still another function,- for as the cross head moves downward the4 links 9 and 'l0 .rotate the connecting bar l1 upon its floating pivot shaft 12 and bring the operating bar 13 within easy reach of the op erator without his changing position. A filial powerful set may be given by the manipulation of this bar 13. The adjustment of the frame S may be such thatthe operating bar may be depressed to suchan 'enA tent that the toggle links will be brought into line and practically self-locked (see Fig. 3). The links are so curved or shaped that they will not interfere with one another in this final closing` movement. lVhen the pressure is completed, the press will remain in this position until the bar 13 is lifted to throw the Said links off center, whereupon the springs 20 and 23. will cause a lifting movement and restore the parts to their The springs'26 force the brim forming member 24 downward, reducii'ig the -pressure on the Aliquid in the bag 28. It is now only necessary to swing the lever Lil to the position shown in Fig. 2 to shift the table 2 toward the operator and to a lower level, thus facilitating the easy removal of the hat thus formed. The dies 24 and 27 being` of solid material preferably metal serve in addition to shaping the hat material to press or nish both the upper and lower surface of the hat brim, while at the same time the walls of the crown receiving recess in the lower die 27 also presses 7 or finishes the outer surface of the crown', hence, simultaneously with the shaping operation, all exposed surfaces of the hat are pressed or finished whereby subsequent operations for this purpose are eliminated.

'ln forming hats of different shapes, it is i necessary to provide dies of dillerent shapes and weight, and to accomn'lodate the return springs 20-20 to the different weights of the upper dies the tension in the spring; 2f? may be adjusted by the sectors 21 and :le

.While I have shown two toggle links 9 and 10, since superior results can be obtained thereby, in the broadest aspect this invexr tion should not be understood as being lim ited thereto.' It will be seen that by this or. equivalentarrangement uniform pressure will be applied to th'e dies in each successive operation of the press.

lVhat l claim is1- l. ln a hat press, two opposed dies, pressuremechanism connected with one of said dies. and means whereby the other of said dies may be moved into and out of the path of and toward and from the opposed die, indemndently of said pressure mechanism.l
